           Summary: Battle.net app takes a long time to start
           Product: Wine
           Version: 6.12
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

I'm using Fedora 33 (Mate) with wine installed from winehq fedora repo.
Starting from wine 6.12, Battle.net application takes a lot of time to start
(more than 5 minutes). When started, it does not render content. Sometimes,
after several attepmts to reload, the content is rendered. The issue persists
in 6.13 and 6.14 too. I tried to install in fresh prefix, but with 6.14, after
more than 10 minutes in state "Updating Battle.net update Agent", I gave up.
With 6.11, installation completed in about 1 minute. Attempt to run from fresh
prefix with 6.14 exhibited the same behavior.
